Basics of Gravimetric and Volumetric Feeding : Plastics

A loss-in-weight feeder is a gravimetric feeder that directly measures the material's weight to achieve and maintain a predetermined feed rate measured in units of weight per time. The following section ( The Gravimetric Feeding Triangle ) introduces the three main challenges faced by any gravimetric feeder: material handling, weighing and control.

Monitoring and Optimizing Fuel Feed, Metering and

Stock Gravimetric feeders provide coal delivery on a weighted basis in order to more closely match the combustion control requirements for heat input into the boiler. The Gravimetric Feeder automatically compensates for density variations and feeds coal to within 1/2% of the true weight.
